An information about my research, a complete publication list and my vita are available.

• My Open Letter (in Slovenian), which was sent to the head of ARIS, Ms. Tjaša Dobnik, on January 8, 2026.
  The reply letter of the head of ARIS sent on February 5, 2026 and also Pangram Lab analysis of the reports received: Report 1, Report 2, and the coordinated report by the referees.
  The letter sent to the head of ARIS on March 22, 2026. This letter is a reaction on the meeting, which took place in SAZU on March 11th, 2026. Its recording is available here.
